General Description: Orange-crowned Warblers (Leiothlypis celata) are sexually monomorphic warblers. They are dull, yellow green with a bit of darker streaking on the breast, a bit of a broken eyering, and a bit of a light eyeline. In breeding season, orange feathers on the crown can sometimes be seen.

Males are brighter yellow than females, and western birds are brighter yellow than eastern birds. In migration through the Las Vegas area, we get a mix such that some birds are much brighter than others.

Taxonomy: Passeriformes, Parulidae. Formerly Vermivora celata and Oreothlypis celata. There are four subspecies, three of which might come through the Las Vegas area. The Pacific subspecies is more yellow, and the Intermountain and Taiga subspecies are more gray, but always have yellow undertail feathers.

Favored Habitat: Often found in shrubby habitats with trees, especially near water.

Where to Find: Corn Creek, Willow Springs, Floyd Lamb State Park, and the Henderson Bird Viewing Preserve.
